The curing effect of a UV furniture dryer is inversely proportional to the conveyor speed. Therefore, in actual production lines, to ensure a balance between speed and quality, at least two or three UV lamps are typically used in combination, with segmented irradiation to achieve uniform curing.

• Single-color wood grain printing machine: Equipped with one printing unit (a set of gravure cylinder + inking doctor blade + embossing roller), it produces one layer of pattern in a single pass. • Two-color wood grain printing machine: Equipped with two printing units, arranged in series. Typically, after the first color, an intermediate curing or short-wave/UV emergency curing period is provided before applying the second color.

A single roller coating machine is a type of roller coating machine that uses a coating roller in contact with the substrate to transfer coating to the surface. A double roller coating machine uses two or more rollers to coordinate coating. The most typical structure is a metering roller and a coating roller, with the coating thickness controlled by a speed difference or pressure between the two rollers.
